i think you're way out of line here. Your're comparing the ramblings of one insignificant individual to the official conduct of a government. these two things shouldn't be campared against each other.

A lot of insignificant individuals have views like her, and they live a few miles from millions of Israelis. If nobody denounces her as a ****ing lunatic, some of them may be bound to act like she suggests. Israelis have good reason to be paranoid and over-protective, since clearly nobody else is going to stand up and defend them when stuff like this happens.
